摘要： In one example, an Edge Quadrature Amplitude Modulation (EQAM) communicates EQAM information to a Modular Cable Modem Termination System (M-CMTS) core using a routing protocol that is configured on a packet switched network coupling the EQAM to the M-CMTS core. The EQAM generates a routing message according to the routing protocol and inserts EQAM information, such as a description of a modulated channel extending from the EQAM, the service-group information, etc, into the routing message. The EQAM then floods the EQAM information over at least portions of a routing domain by transmitting the routing message to an adjacent intermediary device.

摘要： Apparatus, methods, and other embodiments associated with providing service insertion architecture (SIA) differentiated services in a virtual private network (VPN) environment are described. Embodiments may provision an authentication, authorization, and accounting (AAA) server with user-to-SIA service-context mapping information. With the AAA server provisioned, embodiments may acquire, in an IPSec VPN hub, during IPSec tunnel user authentication, from the AAA server, the user-to-SIA service-context mapping information. With the mapping information available, embodiments may dynamically map an SIA service to an IPSec VPN tunnel user based on the service information acquired from the Service Broker or Pseudo-Service Broker. The dynamic mapping facilitates providing differentiated services in the SIA by facilitating forwarding an IPSec packet received on the IPSec VPN tunnel from the user to a service node associated with the SIA service based, at least in part, on the IPSec SADB entry modified using the service information.
摘要翻译：描述了与在虚拟专用网络（VPN）环境中提供服务插入架构（SIA）差异化服务相关联的装置，方法和其他实施例。实施例可以提供具有用户到SIA服务 - 上下文映射信息的认证，授权和计费（AAA）服务器。在提供AAA服务器的情况下，实施例可以在IPSec VPN集线器中从AAA服务器获取用户到SIA服务上下文映射信息的IPSec隧道用户认证期间。利用可用的映射信息，实施例可以基于从服务代理或伪服务代理获取的服务信息来动态地将SIA服务映射到IPSec VPN隧道用户。动态映射有助于在SIA中提供差分服务，方法是至少部分地基于使用该服务修改的IPSec SADB条目，将在IPSec VPN隧道上接收的IPSec分组从用户转发到与SIA服务相关联的服务节点信息。

摘要： In one example, a resource reservation protocol is modified to allow a Modular Cable Modem Termination System (M-CMTS) core to use the protocol to reserve, for a flow, network resources as well as a Radio Frequency (RF) channel extending from the remote PHYsical interface (PHY). The modifications allow the M-CMTS core to identify parameters to be used by the edge device for selecting an available RF channel to be reserved for the flow, or to request a particular one of the RF channels. Intermediary devices operating on the DEPI can also reserve resources for the flow without being reconfigured according to the protocol modifications.
摘要翻译：在一个示例中，修改资源预留协议以允许模块化有线调制解调器终端系统（M-CMTS）核使用协议来为流量预留网络资源以及从远程PHY接口（PHY）。这些修改允许M-CMTS核心识别由边缘设备使用的参数，用于选择要为该流量保留的可用RF信道，或者请求特定的一个RF信道。在DEPI上运行的中间设备也可以为流量预留资源，而无需根据协议修改进行重新配置。
